i looking toward the future. i see a blower motor on a 27-29ft boat. what would be a good exhaust. i like to boat in wisconsin so i would need a good muffler also. does anyone have a good setup that is below 87db?
thanks in advance.

Depending on the HP, we would recommend either Elbow Tops, Sport Tubes or Big Tubes. What CI and HP is the engine?

Try stainless marine gen III manifolds, for supercharged they work well, I have a good used set with 4.5" tailpipes, transom rings and mufflers 2000.00, gg10

I have CMi dry pipes. No complaints. They were wet but I had to go dry to stop reversion in my new motors. Make sure you buy sometheing that fits your future plans.

What muffler system do you use? Has it been inspected by the Water Police and passed and if so at what decibel?

thanks that looks like a good deal. but it'll be a little while before i start to build

i was thinking about a 502 or 496 ho with a procharger and low boost but it's still a ways off.
